Computer keyboards accumulate crumbs and dust quickly—particularly if you're always glued to the screen. A press of this adult version of silly putty, Cyber Clean, can lift all of the crud right from the crevices between keys. Then, simply fold and mold the putty for a clean side to use again. Not only do Cyber Clean's shape-shifting abilities allow it to reach any nook and cranny (USB ports, air vents, between remote control buttons) and wipe out the particles that have accumulated there, but it also makes this one of the most fun cleaning supplies to stock. Available on Amazon; $4.35.
